Merlin,
All I can suggest is that you attempt to restructure the include files
on the next version of the app, so that the functions and includes are
broken in the most logical manner possible (by task or topic for
example), so that you're only including the bare minimum of files for
each request/screen of the app, rather than including a whole bunch of
stuff that may not be needed on every request.
As an example, you might have an include file dedicated to file
uploads, which might be 10 or 20k. It's pointless to include such a
file on every request, since it's only required by a small
module/section of the site. Same goes for your login functions (which
are only required on login and logout), your form validation libraries
(only required when there's a form to validate), etc etc.
You may also decide it's not worth the work... to bench mark, make a
copy of all the code necessary to have a certain part of the site
function, but without grabbing anything unnecessary. Run the site with
the big includes (250k) and run the stripped down version a few times
each (using microtime() for timing it), and compare the results.
If even that sounds like too much work, you may be able to fabricate a
test case using dummy functions and code, which may give some accurate
answers, or may not :)

Hi there,
I am working on a complex webapp written in php. Recently I was
reading about performance issues and after analysing the code I found
that most of the files load 5 external php include files to run. All
together those include files make about 250KB (there are 5 files).
Now I am wondering if loading 250KB on include files, each time a page
= php script is called, is slowing down the webapplication a lot or
not. Is this even
noticable while surfing the site. I am wondering about response times
since I found them a bit slow (the time I click on the link until the
page starts to display).
Thank you for any advice,
Merlin
PS: The system is a p4 2.4G with 1G RAM and about 500.000PI a month.
